be supported in any preferred manner, and this may be accomplished by the use of ya frame 16 secured to the side Wall or ceiling as the case may be, said frame havingvcradle members 17 on which the opposite ends of each element or resonators respectively rest and to which they are secured as at 18, all of which is shown most clearly in Fig. 4.

We claim:

l. An acoustical correction and sound deadening means,comprising the combination with a chamber Wall or ceiling, of series of spaced elements of predetermined potential vibratory responsiveness, positioned With respect to said Wall or ceiling, said series of elements disposed respectively in relatively dilerent planes.

2. An acoustical correction and sound 'deadening means, comprising the combination with a chamber Wall or ceiling, of series of elements having arcuate surfaces of potential vibratory responsiveness, positioned with respect to said Wall or ceiling, said series of elements disposed respectively in relatively different planes.

3. An acoustical correction and sound deadening means, comprising the combination With a chamber Wall or ceiling, of series of spaced elements of predetermined potential vibratory responsiveness positioned With respect to said Wall or ceiling, said series of elements disposed respectively in relatively different planes, and said elements arranged in staggered relationship With respece to each other.

4. An acoustical correction and sound deadening means, comprising the combination with a chamber Wall or ceiling, of series of spaced elements of predetermined poten tial vihratory responsiveness positioned With respect to said Wall or ceiling, said series of elements disposed respectively inrelatively different planes, and said elements arranged in an overlapping relationship.

5. An acoustical correction and sound deadening means, comprising the combination with a chamber Wall or ceiling, of series of resonators disposed respectively in relatively dierent planes, and positioned with respect to said Wall or ceiling, each of said resonators having an arcuate surface ci alo sorbent material having a relatively high cc= p eciency of sound absorption.

6. An acoustical correction vand sound deadenin'g means, comprising the combination with a chamber Wall or ceiling, series of spaced elements or predetermined potential vihratory responsiveness positioned with respect to said wall or ceiling, said series of elements disposed respectively in relatively diderent planes and reversely arranged with respect to each other.
